Hello people of the internet. Will Richard here blogging away about a favourite of mine from the Grant Museum’s collection. This week I’ve chosen a specimen that’s a little bit of everything: dog, fish, cat and shark. That’s right folks, so good they named it twice, it’s the…

This week in The Conversation I wrote that there is no biological definition of fish that doesn’t involve humans. However the group that most people recognise as the fishiest are the ray-finned fishes. They have fins supported by a series of fine flexible rods. It is the ray-fins that have gone on to be the dominant vertebrates in the seas, lakes and rivers: there are around 30,000 species. This makes them by far the most diverse vertebrate group, and I’d like to explore how that happened. Among them is this week’s Specimen of the Week:

These are troubling times. Troubling and worrying times. Hope is an endangered species. You can feel it can’t you? Spin the wheel of woe, the only consolation possible is that you guessed correctly what destroyed the privileged civilisation as we know it. Was it climate in the end? Was it hatred? Was it intolerance? It doesn’t matter now of course. You’ll realise then what you suspect now, childish notions of justice winning out in the end were just that. There is no beacon of light on the horizon. In fact, the future is so pitch black in its nothingness that the next step could be the one into the abyss and you wouldn’t even know. So look to the horizon now, it’s petrifying isn’t it?

‘Natural Creativity: Sex and Trickery’ is our new exhibition – opening tomorrow 19th October – at the Grant Museum. It explores the myriad of elaborate shapes, sizes and crafty behavioural tactics some animals have evolved in order to survive, reproduce and pass on their genes.

Ocellated wrasse (C) Clara Lacy.The ocellated wrasse has an unusual mating system – different males use different strategies in the attempt to pass on their genes. The genetics of these strategies is being researched at UCL. “Nesting males” are brightly coloured and work to court females, defend nests and care for their young. These males attract the most females, but other males have evolved different routes to mating success.Small males become “Sneakers”. They surreptitiously approach Nesting males and females while they are mating, and then release their own sperm into the water.Medium-sized “Satellite males” cooperate with a Nesting male, helping them chase Sneakers from the nest. This means that they are tolerated by Nesting males, and spawn while the Nesting male is mating.

In a few days time the autumn term at UCL begins along with the many classes and practicals which take place in the Grant Museum. In the first term of last year, the Grant Museum held 28 specimen-based practicals using 770 specimens. Over 1300 UCL students from various departments attended these practicals as part of their course work.

To celebrate the return of the autumn term, here’s a specimen which will be used several times in the next few months in the ever-popular Vertebrate Palaeontology and Evolution. This week’s Specimen of the Week is… (more…)

1. Familiar when fleshless

Can you name some animals that look more or less the same with or without their skin and flesh on? Those which are instantly recognisable from their skeletons alone?
Crocodiles, penguins and seahorses spring to my mind. Can you think of any more?
What these unrelated animals have in common – and what sets them apart – is that their skin sits directly on bone, at least on the important bodyparts. But this comes about in different ways.

There are quite a few posts on this blog regarding not-so-lovely fossil fish, which might possibly lead one to believe that the Grant Museum’s collection does not include fossil fish specimens of outstanding beauty. This is, however, definitely not the case. The Museum has many finely detailed, historically interesting, painstakingly prepared fossil fish – specimens that would, in fact, be described as anything but underwhelming.

Hello dear Specimen of the Week readers, Dean Veall here. This week I shall be bringing you a very fishy (again) Specimen of the Week, how can I possibly top the three toothed pufferfish you may be asking yourself? Well, I believe I have for two very good reasons. Firstly the fish I have chosen is one of the asymmetrical marvels of the natural world. Secondly, has one of the most curmudgeonly comical faces of all animals (I challenge you to find me an animal that beats this specimen). And finally, has recently featured in the events that have accompained our Glass Delusions exhibition. This week’s Specimen of the Week is…..
